Function of Ultrasonic Sieving Machine

Ultrasonic sieving machine is suitable for 400 mesh, 500 mesh and 600 mesh fine materials, such as graphite powder, diamond, glass powder, silica alumina powder, slurry, white latex, alumina, quartz sand, lithium battery cathode material, metal powder, fluorescent Powder, titanium powder, trace mineral powder, sulfur powder, high nickel ternary cathode material, epoxy powder, traditional Chinese medicine powder, catalyst, lithium battery powder, stainless steel metal powder, chili powder, diamond, matcha powder, etc.

ultrasonic system

1. Ultrafine powder screening: It really solves the screening problems of materials with strong adsorption, adhesion, viscosity, high static electricity, high density, ultrafine powder and other characteristics.

2. Solve the clogging of the screen: The ultrasonic system applies high-frequency, extremely low-amplitude vibration to the screen, and the vibration frequency is 36,000 times/min, which helps to deblind and fluidize fine products, making it easier to screen.

3. Cost reduction: Due to the elimination of screen clogging, the product quality remains consistent throughout the production process, and there is no need to stop the machine to clean the screen, reducing the risk of downtime and reducing production costs.

4. Increase the output: Since the screen will not be blocked, the screen can be cleaned without stopping, and the output can be increased by 0.5-10 times.

Working Principle of Ultrasonic Sieving Machine

Ultrasonic sieving machine converts 220V, 50Hz or 110V, 60Hz electric energy into high-frequency electric energy such as 18KHz, inputting the ultrasonic transducer, and turning it into mechanical vibration such as 18KHz, so as to achieve the purpose of efficient screening and net cleaning. It eliminates the static electricity on the screen holes, the agglomeration of powder and the clogging problem caused by the particles inserted into the rough mesh surface, and does not change the characteristics of the screened material.

The frequency conversion device is to change the vibration frequency of the ordinary sieving machine, so that the vibration frequency of the material in the same unit time increases, thereby increasing the number of times the material passes through the sieve holes in the same time, making the sieving machine more efficient and finer, suitable for wider range.

Advantages of Ultrasonic Sieving Machine

Prevent blindness and blockage

Use ultrasonic frequencies to vibrate the mesh so that the mesh does not clog, while allowing separation accuracy down to 20 μm (#635 mesh).

Increase production

Ultrasonic sieving can make the powder pass through the sieve holes faster and increase the mesh penetration efficiency, thereby increasing the sieving capacity by 10 times.

Continuously working

The power supply can be adjusted automatically between 18K-40K, and the low frequency can be converted to high frequency according to the specific gravity of the material. The transducer can work continuously for 12-24 hours.

Upgrade existing systems

Can be installed onto new or existing shakers for easy integration into your production line.

Avoid production downtime

Preventing screen overloading not only reduces production downtime, but also reduces the time required to clean the screen.

Reduce operating costs

There is no need to clean the net with a rubber ball to prevent re-contamination caused by rubber abrasion.
